22. design suitable for street light and home light.

23. battery charging indications

● green led – charging. (blinking)

● red led – low battery and short circuit.

● both glow together if any fault like open load or short circuit.

24. auto reconnect bms to solar charge controller in case of a battery cut off via bms (0 vdc output from the battery) to avoid service engineer frequent site visit.
